Mute key not working anymore on T61

[Cyril Jaquier <cyril.jaquier@jaqpot.net>]

Hi all,

Since a few days (weeks?), my mute key does not work anymore. Volume up 
and down work as expected. xev just says nothing while pressing this 
key. I reported this here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=460564

However, I can't remember if the mute key used to generate an ACPI event 
or was monitored by thinkpad-keys!?

Dear Lenovo T61 users, do you have a working mute key under unstable?

Thanks,

Cyril Jaquier
